摘要：

The influence of tin on the thermoelectric properties of p-(BixSb1-x)(2)Te-3 single crystals (x=0; 0.25; 0.5) has been investigated. The temperature dependence of the Seebeck coefficient S. the electrical conductivity sigma, the heat conductivity k and the thermoelectric figure of merit of p-(BixSb1-x)2Te3 single crystals were measured in the temperature range 7-300 K. By an increase the Sn content, the hole concentration increases in p-(BixSb1-x)(2-y)SnyTe3. The heat conductivity k of the p-(BixSb1-x)(2-y)SnyTe3 crystals decreases due to the Sn doping, while the electrical conductivity sigma increases in the temperature interval about 200 < T < 300 K and decreases at T < 200 K. The Seebeck coefficient S for all compositions is positive and decreases due to the Sn doping in the whole temperature range. The scattering on the ionized impurity increases due to Sn doping.
